From b1eeb38e456281c37bbfc270a6ca08605b7e7045 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Fri, 26 Jan 2007 19:08:12 -0800 Subject: [PATCH] [POWERPC] ps3: add interrupt alloc for outlets PS3 interrupt core update: - Add ps3_alloc_irq() and ps3_free_irq(), to allocate a virtual interrupt number for an interrupt outlet, which is needed by the PS3 GPU frame buffer device and audio drivers Signed-off-by: Geert Uytterhoeven Signed-off-by: Geoff Levand Acked-by: Arnd Bergmann Signed-off-by: Paul Mackerras --- arch/powerpc/platforms/ps3/interrupt.c | 24 ++++++++++++++---------- include/asm-powerpc/ps3.h | 3 +++ 2 files changed, 17 insertions(+), 10 deletions(-) diff --git a/arch/powerpc/platforms/ps3/interrupt.c b/arch/powerpc/platforms/ps3/interrupt.c index 27afd1f..3735cd1 100644 --- a/arch/powerpc/platforms/ps3/interrupt.c +++ b/arch/powerpc/platforms/ps3/interrupt.c @@ -85,7 +85,7 @@ struct ps3_private { static DEFINE_PER_CPU(struct ps3_private, ps3_private); -static int ps3_connect_irq(enum ps3_cpu_binding cpu, unsigned long outlet, +int ps3_alloc_irq(enum ps3_cpu_binding cpu, unsigned long outlet, unsigned int *virq) { int result; @@ -138,8 +138,9 @@ fail_connect: fail_create: return result; } +EXPORT_SYMBOL_GPL(ps3_alloc_irq); -static void ps3_disconnect_irq(unsigned int virq) +int ps3_free_irq(unsigned int virq) { int result; const struct ps3_private *pd = get_irq_chip_data(virq); @@ -155,7 +156,9 @@ static void ps3_disconnect_irq(unsigned int virq) set_irq_chip_data(virq, NULL); irq_dispose_mapping(virq); + return result; } +EXPORT_SYMBOL_GPL(ps3_free_irq); /** * ps3_alloc_io_irq - Assign a virq to a system bus device. @@ -182,7 +185,7 @@ int ps3_alloc_io_irq(enum ps3_cpu_binding cpu, unsigned int interrupt_id, return result; } - result = ps3_connect_irq(cpu, outlet, virq); + result = ps3_alloc_irq(cpu, outlet, virq); BUG_ON(result); return result; @@ -198,7 +201,7 @@ int ps3_free_io_irq(unsigned int virq) pr_debug("%s:%d: lv1_destruct_io_irq_outlet failed: %s\n", __func__, __LINE__, ps3_result(result)); - ps3_disconnect_irq(virq); + ps3_free_irq(virq); return result; } @@ -228,7 +231,7 @@ int ps3_alloc_event_irq(enum ps3_cpu_binding cpu, unsigned int *virq) return result; } - result = ps3_connect_irq(cpu, outlet, virq); + result = ps3_alloc_irq(cpu, outlet, virq); BUG_ON(result); return result; @@ -246,7 +249,7 @@ int ps3_free_event_irq(unsigned int virq) pr_debug("%s:%d: lv1_destruct_event_receive_port failed: %s\n", __func__, __LINE__, ps3_result(result)); - ps3_disconnect_irq(virq); + ps3_free_irq(virq); pr_debug(" <- %s:%d\n", __func__, __LINE__); return result; @@ -350,7 +353,7 @@ int ps3_alloc_vuart_irq(enum ps3_cpu_binding cpu, void* virt_addr_bmp, return result; } - result = ps3_connect_irq(cpu, outlet, virq); + result = ps3_alloc_irq(cpu, outlet, virq); BUG_ON(result); return result; @@ -368,7 +371,7 @@ int ps3_free_vuart_irq(unsigned int virq) return result; } - ps3_disconnect_irq(virq); + ps3_free_irq(virq); return result; } @@ -399,7 +402,7 @@ int ps3_alloc_spe_irq(enum ps3_cpu_binding cpu, unsigned long spe_id, return result; } - result = ps3_connect_irq(cpu, outlet, virq); + result = ps3_alloc_irq(cpu, outlet, virq); BUG_ON(result); return result; @@ -407,10 +410,11 @@ int ps3_alloc_spe_irq(enum ps3_cpu_binding cpu, unsigned long spe_id, int ps3_free_spe_irq(unsigned int virq) { - ps3_disconnect_irq(virq); + ps3_free_irq(virq); return 0; } + #define PS3_INVALID_OUTLET ((irq_hw_number_t)-1) #define PS3_PLUG_MAX 63 diff --git a/include/asm-powerpc/ps3.h b/include/asm-powerpc/ps3.h index 021f802..00a4c7d 100644 --- a/include/asm-powerpc/ps3.h +++ b/include/asm-powerpc/ps3.h @@ -163,6 +163,9 @@ int ps3_free_vuart_irq(unsigned int virq); int ps3_alloc_spe_irq(enum ps3_cpu_binding cpu, unsigned long spe_id, unsigned int class, unsigned int *virq); int ps3_free_spe_irq(unsigned int virq); +int ps3_alloc_irq(enum ps3_cpu_binding cpu, unsigned long outlet, + unsigned int *virq); +int ps3_free_irq(unsigned int virq); /* lv1 result codes */ -- 2.7.4
